Codelab! writing definition of a function

[dougok07]

Here is the problem I'm working on


Your task here is to write the definition of a function called getElectoralVotes . The function receives a two-character string (like "NY") and returns the number of electoral votes the indicated state has.

The function accomplishes this by doing the following:
open up the ev.txt file
read the state string and votes integer in each line in that file
when it finds a state in the file that matches its parameter (the state abbreviation) it returns the integer from that line in the file
if it does not find a match it returns 0
finally, the function should close the file when it is finished using it

So, if the ev.txt file contained:

      NJ 8
      NM 3
      NY 32

then
getElectoralVotes("NJ") would return the value 8
getElectoralVotes("NY") would return the value 32, and
getElectoralVotes("ON") would return the value 0

Here is what I have so far: (Not looking for answers just direction)

int getElectoralVotes(string state){
	ifstream evFile("ev.txt");
	string Fstate;
	int votes;
	
	evFile>>Fstate;
	evFile>>votes;
	cin>>state;
	while (!evFile.fail()) {
	if(Fstate==state){
	return votes;
	evFile>>Fstate;
	}
	else if(!(Fstate==state)){
	return 0;
	evFile>>Fstate;
	}
	evFile.close();
	}
        }

ERROR Message:

Remarks:
     ⇒     Fails on AK returning 0 instead of 3

     ⇒     Your code had an error during execution

Please put [code][/code] tags around your code.

Your function looks like it reads the first state/vote pair and returns the votes if it matches the input (the evFile>>Fstate afterwards does nothing as the function has returned) and if it doesn't it returns 0 without checking the rest of the file.
